31V DC SSR?

Hi, I want this to be my first year at starting to sequencing some of my Christmas lights. I have a number of 31V DC "LED blossom trees" that I want to sequence. so the big question is where can I find 31V DC SSR? would i be able to convert the DCSSR ([font=verdana, arial, helvetica, sans-serif]http://doityourselfchristmas.com/wiki/index.php?title=DCSSR_Version_2.4) to 31V ? I see the [/font]MOSFET's are 60V but i'm guessing one just cant wire 31V into it as is?

I used about 20 of my existing blossom trees and led strings last year that were 31vdc with my Falcon v16 board. You will need a dc board and I used the Hanson DMX36 board. Worked perfect. Has 36 outputs available and used a 31vdc power supply.
